On one hand, this kind of mountain fortress project did not need to be as long as the tunnel. Most of them were tunnels, and the tunnels were no more than 50 meters deep near the ridge of the mountain top. There was no problem with underground water, so they could just drill through.
Moreover, this kind of construction could still be improved.
They could also build hidden fire points on the mountainside and at the foot of the mountain. The various fire points would cover and cooperate with each other. A few small bunkers could be built inside the valley entrance.
No matter how tough the Japanese were, they could forget about attacking from the entrance of the valley.
"Battalion Commander, what if the Japanese don't go through the valley entrance and climb over the mountain?”Zhang Jiyong asked. He felt that it was not very reliable.
"That's why we still have to build a defense line on the mountain, similar to this defense line that blocks the entrance. As long as we make good use of the front and back slopes and build Y-shaped or H-shaped tunnels according to the terrain, we can use a small number of troops to block the Japanese's attack.”Su Yang said.
The Battle of Shanggan Ridge used this tactic. The rabbit army fought in a hurry, but they were faced with the terrifying heavy firepower of Yingchan. The rabbit army made use of the anti-slope tactic and successfully defended the line of defense. Yingjiang's artillery fire flattened the top of Shanggan Ridge by three meters. However, the rabbit army used the tunnels to protect themselves. Moreover, the casualties were not high. Instead, Yingjiang paid a huge price.
This tactic was to build Y-shaped and H-shaped tunnels on the top of the mountain, and use the tunnels to open up the positive slope, the reverse slope, and the high ground of the mountain top to form a network of tunnels that extended in all directions.
The rabbit army used this tactic to shift their troops to the reverse slope when the Ying-chan artillery bombarded them. The artillery shells would usually be blocked by the mountain. As for Ying-chan, once she got close to the enemy's position and started firing at a high angle, she would quickly move her people to the front slope to counter.
The rabbit army usually only needed to send in a group of three to four people to defeat an entire platoon of Ying-chan. A squad could deal with the charge of Yingchan's entire company. After all, the enemy had climbed up the mountain, so their speed was very slow. This kind of high mountain position had great terrain suppression. Even if a random stone was thrown down, it could easily kill someone. If a grenade was thrown down...
At the same time, on the fortifications on the front slope, they could also build fire points on the reverse slope.
It was as if there was Yang in Yin and Yin in Yang.
This kind of counter-slanting tactic was actually a skillful way of Yin and Yang.
The enemy's cannons firing from a long distance on the inclined side was a kind of 'dark' tactic, while the defenders hid on the opposite side of the mountain, which was equivalent to borrowing the 'dark' of the mountain terrain. No matter how strong a person's Yin and Yang were, they could not defeat nature's Yin and Yang in many cases, unless the technology was very advanced, such as when there were a large number of earth-piercing bombs. And when people were on the reverse slope, they did not need any cover, and it was yin with yang.
In a confrontation between Yin and Yin, the enemy could not do anything to the defender.
Then, the enemy's attack and the artillery fire at a high angle were equivalent to the 'Yang' tactic. At this time, the defending side would enter the positive slope and switch to the positive mode. They would use the 'Yang' of the mountain terrain to confront the enemy's Yang. At this time, the defending side would hide in the fortifications of the positive slope, and it would be Yang with Yin.
When the enemy's artillery fire was aimed at the front of the camp, it would turn into a " Yang " attack. Meanwhile, the enemy's artillery fire would be hidden in the safety position behind the anti-slope to fire at the enemy artillery. It was another Yin attack Yang.
This kind of battle technique of 'Yang VS Yang' and 'Yin VS Yin', with Yang carrying Yin and Yin carrying Yang, depended on whether the terrain was strong enough.
In the first half of the 20th century, although science and technology had developed, humans were still unable to defeat nature in military affairs. In terms of supplies, defense, climate, and other aspects, they were still strongly influenced by nature. The Japanese's firepower was obviously not as good as Ying-chan's, and the difference was like heaven and earth. On the other hand, Su Yang's firepower was even stronger than the rabbit army in the original space-time.
The rabbit army had made hasty preparations during the Battle of Shanggan Ridge, so their machine gun firepower was not strong. On the other hand, Su Yang had crazy machine gun firepower.
In the Dao of Yin and Yang in war, the defending side had to protect themselves. It was nothing more than using Yang against Yang and Yin against Yin.
When Yin fought with Yin, the Yin did not have any vitality. It was equivalent to both of them being " still ". How could one side hurt the other? It was just like how the enemy's artillery fire would only fly over the top of the mountain when the people were hiding on the slope. The enemy's artillery fire would not come into contact with the people on their side at all, so there was no harm.
When Yang and Yang fought, it was a violent collision, like two objects colliding. The faster the speed, the higher the height (Yang), and the harder the quality (Yin) of one party, the stronger the opponent would be. It was like a car hitting a person at high speed. The car would definitely kill the person.
By understanding the Dao of Yin and Yang, the defenders could counter every move and adapt flexibly. If the defending side could borrow enough Yin and Yang energy, they could defeat the stronger side.
How could the attacker destroy the enemy?
The secret was to use Yang to attack Yin and Yin to attack Yang.
For example, the attacking side using artillery fire to attack the defending side's front slope was a kind of Yin attacking Yang. At the same time, artillery fire had a powerful kinetic energy, and it was Yin with Yang.
For example, when the enemy was charging on a slope, the enemy was exposed to the enemy's eyes, so it was a kind of yang. However, the enemy was from a low altitude, and the defender was from a high altitude, so the enemy had a yin side. On the other hand, if one's side was at a high altitude, it would be a positive sign. At the same time, one's side would be protected by cover and would not be directly exposed to the enemy's sight, so it would be a negative sign.
Under such circumstances, the enemy would only be able to see the sun, and they would be beaten up while standing. The Yang attribute of the defending side was the Yang attribute of the terrain given by the mountains and rivers. They occupied the high ground and attacked the enemy that was exposed in front of them. They completely crushed the enemy on the Yang attribute. In terms of Yin, the enemy's Yin was given by the low altitude and did not have the ability to defend. On the other hand, the Yin attribute of the defending side was given by the fortifications, so it had a strong defensive ability.
As the saying goes,'soldiers have no constant momentum, and water has no constant shapes'. To put it bluntly, war is a model of energy movement. The energy of both sides is constantly changing. Whoever was more compatible with this energy movement model would win. This was the same as the nature of fighting sports.
Ever since Fuxi created the Eight Trigrams, the Chinese had already established such an energy analysis tool. Therefore, since ancient times, China had never emphasized logical thinking. Instead, it emphasized analogy.
The Chinese language and characters were a compilation of nature, and they were born to train logical thinking. Using this energy model tool to simulate reality was a kind of analogy thinking.
The logical thinking was like a line, while the analogy thinking was like a surface. Lines were contained in the surface. If a person only knew how to use logical thinking and had a mess of analogy thinking, his IQ would definitely not be high.
The reason why Westerners emphasized logical thinking was because their language and words were a kind of computer language. Their logical thinking could not be trained by language and words, so their intelligence was like a group of carbon-based IAs.
Of course, it was not that Westerners did not have outstanding intelligence, but their ability to think by analogy was purely a test of the brain's hardware.
On the other hand, not only did the Chinese surpass the Westerners in terms of brain intelligence, but they also had a set of analogy thinking tools such as Yin-Yang, Five Elements, Zhouyi, and Eight Trigrams. It was equivalent to crushing the Westerners in terms of software.
It was as if the Chinese had mastered a set of formulas to analyze the rules of energy movement. This formula could endlessly derive energy movement. On the big level, there were Taiyi, Yin-Yang, Four Seasons, Five Elements, Eight Trigrams, Sixty-Four. On the small level, there were 512 hexagrams, 4096 hexagrams, 32768 hexagrams... there were no limits.
As for the legendary and extremely awesome Guigu 'zi, he had only used 512 hexagrams in divination. The rest was too complicated, and it had already exceeded the limits of the human brain and lifespan.
War was like this. Victory and defeat were never determined by strength, but by the combination of intelligence and strength. The reason why the rabbit army was able to win against foreign enemies with outdated equipment was because of their intelligence, not because they relied on human wave tactics. The rabbit army did not advocate human wave tactics. The three-three-three tactic was a model of small group assault and flexibility.
The essence of war was the movement and consumption of energy. Humans could not only rely on the energy of objects, but also the energy of time and place. Harmony was the basic way to increase their own strength.
The people of China had fully recognized this point in ancient times, so they said,'The weather, the terrain, and the people are the same. If you get one, you can stabilize the other, if you get two, you can stabilize the country, and if you get three, you can pacify the world'.
If Su Yang wanted to keep his base from being swept away, he naturally had to make use of the geographical advantage of the Changbai Mountain range.
